GENERALModel LFS1300, Control Function for Standard Field Control Station (for FIO), is installed and runs in any of the following FCS models: AFS30S, AFS30D, AFS40S, AFS40D

FUNCTION SPECIFICATIONS Structure of Control FunctionsThe basic control functions are implemented as a two-level hierarchy, described below. Such a hierarchical model facilitates engineering and modification/addition of functions.

Function BlocksThese are the smallest elements used to perform control and calculation, and are at the bottom of the hierarchy.

Control DrawingA control drawing represents the control instruments responsible for overall control of a small section of the plant, and typically contains several function blocks. A control drawing may be used to implement cascade control or combustion fuel/air ratio control, for example.

Function BlocksThe function blocks are divided into regulatory and sequence control blocks, calculation blocks, faceplate blocks and unit instruments. These function blocks may be combined to configure a control drawing.

Extended hybrid manual station: Has the functions of triple-pointer operating station and 5-push-button switch.

Enhanced MC/Switch Instrument BlockThese blocks include enhanced versions of functions incorporated in normal ON/OFF controller blocks, motor control blocks, switch instrument blocks to facilitate mi-grating from a competitor’s control systems, or to allow the control of DO blocks (on/off valve, etc.) in a fieldbus device from ON/OFF controller blocks, MC instru-ments, or switch instruments. In addition to functions in normal instruments, the following functions are added. Enhanced MC/Switch Instrument blocks are standard functions and need optional memory areas of 64 KB when they are used.

Foundation Fieldbus Faceplate Block Connectivity: Enhanced function blocks in a field control station for FIO can connect DI and DO blocks in a fieldbus device via a faceplate block.

Individual Wiring: The open/close or open/close/stop signals for 2-position pulsive outputs, or 3-position (pulsive or status) inputs or outputs of a standard function block can only be connected to contiguous terminals on the same module. For an enhanced function block, however, these input and output signals can be independently con-nected to arbitrary terminals.

For migration from other company’s con-trol systems, enhanced ON/OFF control-lers, enhanced motor control blocks, and enhanced switch instrument blocks can be connected without needing rewiring even though cards with open and close signals from different cards are connect-ed.

Masking of Answerback Undefined Alarm (PERR): Checking of the answerback undefined alarm (PERR) is overridden for a preset time after an open or close (or run or stop) action. Where a Foundation fieldbus faceplate block is connected, or where the answerback signals of a field device are input from different modules, the simulta-neity of those answerback signals cannot be assured. In these cases, masking the PERR alarm check will prevent unneces-sary alarms from occurring.
